COIN-CONTROLLED LOCK.

SPECIFICATION forming part of Letters Patent No. 499,803, dated June 20, 1893. Application filed March 8, 1893. Serial No. 465,082. (No model.)

To all whom it may concern:

Be it known that I, WINFIELD S. ROGERS, of Troy, Rensselaer county, New York, have invented certain new and useful Improvements in Coin-Controlled Locks, of which the following is a specification.

This invention relates to improvements in looks the object being to render the key inefiectual in'opening the lock until a coin, or equivalent piece, has been placed within the lock. Aside from the utility of the device as alock requiring, in effect, two keys for its op-' eration, it has merit as a trick lock for amusement purposes.

My improvement will be readily understood from the following description taken in con? nection with the accompanying drawings which illustrate a pad-lock exemplifying my invention, Figure 1 being a face view of the lock; Fig. 2, a view of the key; and Fig. 3, a face view of the lock with the front plate removed.

In the drawingsz-A, indicates the shell of the lock; B, the shackle; C, the latch-piece to engage the shackle, by spring force, and prevent the opening of the shackle while so, engaged, the latch-piece in the exemplification being shown as formed in one piece to serve at once as latch-piece and spring to operate in a manner clearly obvious from the drawings; D, the key, having a bit too short to have efiect upon the latch-piece; E, a slot in the shell of the lock adapted to permit the passage of a coin or equivalent piece; and F, a coin or, equivalent piece which has been dropped into the slot E, before the key was entered, the coin, when thus present, serving as an intermediate-connection between the key and the latching-mechanism whereby the key, when turned, exerts a pressure upon the coin, which, in turn,'exerts a releasing pressure upon the latching-mechanism. The slot E is to be so disposed that the coin can be passed into the look while the shackle is latched. The coin may be removed through the slot E.

I claim as my invention-- The combination, substantially as set forth, of a lock case provided with a slot, through which a coin may be inserted into and removed from the case at will a shackle connected therewith, a spring-held latch-piece within the lock case and normally engaging the shackle, and a key provided with a bit too short to affect the latching mechanism direct but of a length to affect it through the intermediacy of a coin or equivalent pieceinserted in the lock case through the slot.
